If you go into the game options, you can change the shooting controls to 'Real Player %', which means instead of using the 'Shot Stick Timing' for your shooting, it takes the players attribute ratings into account instead of you controlling the analog stick to shoot.

Never used the player % option, the shot stick gives you a wide range of options when shooting and allows you to change your shot when hit instead of having the game do it for you, I've always prefered that to one button shooting like in NBA Live.

The hardest part is getting the timing down, especially for players with fucked up shooting motions (Brewer, Marion, Noah, MKG) but when you get it, its the best thing about offense.
